Key takeaways
  • Once a court finds that one partner was unjustly enriched at the other's expense, it has to decide how to fix that unfairness.
  • A monetary award is the more common outcome.
  • A constructive trust is a different kind of remedy — it doesn't just compensate the claimant, it recognizes them as a partial owner of a specific property, most often a home.

When an unmarried couple separates in Ontario and one partner has a successful unjust enrichment claim, the next question is just as important as winning the claim itself: what does the court actually order? There are two main possibilities — a monetary award, or a constructive trust giving the claimant an ownership interest in specific property. They can lead to very different outcomes, especially when property values have changed since separation.

Understanding the difference helps you set realistic expectations about what a successful claim might actually get you.

Two Ways a Court Can Remedy Unjust Enrichment

Once a court finds that one partner was unjustly enriched at the other's expense, it has to decide how to fix that unfairness. Broadly, it has two tools:

Both remedies flow from the same underlying finding of unjust enrichment. The difference is in what you actually walk away with.

Monetary Award: The Default Remedy

A monetary award is the more common outcome. The court calculates a dollar figure meant to compensate the claimant — either for the value of what they contributed (a "value received" approach) or for a proportionate share of accumulated wealth where the relationship functioned as a joint family venture (a "value survived" approach).

A monetary award is generally preferred when:

Constructive Trust: An Ownership Interest Instead of Cash

A constructive trust is a different kind of remedy — it doesn't just compensate the claimant, it recognizes them as a partial owner of a specific property, most often a home. This matters because it lets the claimant share directly in that property's value, including any appreciation after separation, rather than being limited to whatever dollar figure a court calculated as of the separation date.

Courts generally reserve a constructive trust for situations where:

When Courts Choose One Over the Other

Courts weigh several considerations when deciding between the two remedies:

  1. Traceability — can the contribution be linked directly to a specific asset, or was it more general (unpaid household labour, general household expenses)?
  2. Fairness of a dollar figure — would a monetary award undervalue the claimant's real stake, particularly where the asset has appreciated?
  3. Practicality — does the paying partner actually have the money to satisfy a monetary award, or would enforcement realistically require dealing with the property anyway?
  4. Proportionality — is the contribution significant enough to justify an ownership interest, rather than compensation?

Frequently asked questions

Can I ask for a constructive trust if my name was never on title?

Yes — a constructive trust is specifically designed for situations where legal title doesn't reflect the true contributions behind a property. Not being on title doesn't prevent a claim; it's often the reason the claim exists.

Which remedy is "better"?

Neither is automatically better — it depends on the facts. A constructive trust can be more valuable if the property has appreciated significantly, but a monetary award may be simpler to enforce and doesn't require dealing with a jointly used property.

Can a court award both a monetary payment and a share of a property?

Courts generally choose the remedy that fits the facts of the case rather than layering both for the same contribution, but the specific relief awarded depends heavily on the circumstances. This is a question to work through with a lawyer based on your facts.

Does it matter if the property was purchased before the relationship started?

It can. Contributions made during the relationship toward a property one partner already owned can still support a claim, but the analysis is more nuanced than for property acquired jointly during the relationship.
